I doubt any of this is groundbreaking. Story structure is a widely studied topic (and one that I find fascinating). But it seems like Dan Brown uses a very well defined, customised version of this, that makes for engaging, fast-paced books.

I sort of proved (for myself, at least) that this works, by writing a novel whose structure was originally based on this pattern (although it later diverged a bit), and which causes the expected effect - a couple of readers have read it in a single sitting :)
